* fix(deps): pin openai==2.44.0 to avoid InputTokensDetails breaking change (#187)

openai 2.45.0 added a required, no-default field cache_write_tokens to
InputTokensDetails. openai-agents 0.17.3 builds that object without the
field, so every LLM response crashes usage parsing with a pydantic
ValidationError. openkb did not pin openai, so fresh installs resolved it
to 2.45/2.46 and broke on any model. Pin below 2.45 until openai-agents
adapts.

* chore(deps): update uv.lock for openai==2.44.0 pin (#187)
